(Cl. 282-1) This invention relates lto a manifolding carbon holder and more particularly to a carbon holder adapted to be interleaved in superposed relation with stn'ps of continuous form stationery for use in a typewriter or other writing machines for making multiple copies.

This invention is a carbon holder of a type to be used with multiple plies of continuous form stationery when -it is desired to make multiple typewritten copies thereof. In the standard form of this device strips of continuous form stationery are interleaved with the carbon holder and the resultant assembly is inserted in a typewriter. information is then typed on an individual form length, lthereby making multiple copies thereof. When the desired information has been imparted to an individual form length the typewriter platen is thrown out of frictional engagement with the driving rollers and the stationery is manually advanced past the carbon sheets, one form length by the typist. The platen is then thrown back into frictional engagement with the driving rollers and the stationery and carbon pack are reversed to a point where the next succeeding individual form length Vis in a position where it is ready to receive typed information. At this point the previously typed form length and its multiple copies, which now protrude above the carbon pack, are torn off along a transverse line of weakening and separated from the continuous strip. This process is repeated until the desired number of form lengths have been typed.

Carbon holders in current use are generally constructed so that a portion of the body of the holder lies in superposed relation with the stationery as it passes between the typewriter platen and driving rollers. This creates an excessively bulky pack and when the Atypist attempts to throw the platen out of frictionm engagement with the driving rollers in order that she may manually pull the continuous form stationery forward one form length, the bulk is usually so great that the platen does not become completely frictionally disengaged with the driving rollers. Thus it is extremely diiiicult, if not impossible, for the stationery to be pulled forward `one form length without pulling the carbon pack along with it. Present units are also limited in the number of multiple plies of continuous form stationery with which they may be used. 1furthermore, carbon holders in current use are not so constructed that they can be conveniently stored in assembled relation with a stack of continuous form stationery due to the fact that the carbon sheets are usually mounted on generally rigid bars which extend beyond the width of the continuous form stationery, resulting in cumbersome extensions to an otherwise generally trim stack of material.

lt is the primary object of this invention to provide a new `and improved carbon holder device.

It is another object of this invention to providea new and improved carbon holder device which can be combined with like units for making more multiple copies than can be made with one unit.

It is a further object of this invention to provide a new and improved carbon holder device which can be preloaded with continuous form stationery and yet retain a generally trim com'iguration which conforms substantially to that of the stack of stationery interleaved therein for the convenience of shipping or storing.

It is still another object of this invention to provide a ice new and improved carbon holder device which, when interleaved with continuous form stationery and inserted for use in a typewriter, will allow yeasier manual pulling forward of a form length of continuous stationery when the typewriter platen is Itaken out of frictional engagement with the typewriter driving rolls.

It is a yet further object of this invention to provide a new and improved carbon holder device consisting of a staple part and an inexpensive consumable part, wherein the inexpensive consumable part may be disposed of and easily replaced when spent.

Further objects, features and advantages of the invention will be readily apparent from the following specification taken with reference to the drawings, in which:

The device of this invention is a carbon holder of a class designed to be used with strips of continuous form stationery in making multiple typewritten copies of individual form lengths thereof. The carbon holder of this invention, gener-ally indicated at 10, includes a plurality of transfer material holding means or bars l11 of semillexible material such as paper or cardboard which is adapted to retain its shape for securing transfer material means or carbon sheets 12 thereto. Guide means or trailing bar 11a, which is similar to bars 11, is positioned rearwardly from the bars 11 for maintaining alignment of the carbon sheets and stationery interleaved therebetween. The bars are separated by stationery receiving means or spaces 13 for threadably receiving strips of continuous form stationery 41. Both the bars and interposed spaces are wider than carbon sheets attached to the bars or stationery intended to be threaded therebetween. The bars 11 are integrally joined at their extremities to margins 14 of like ilexible material which extend rearwardly in elongate thin strips of flexible material to form side straps 'l5 and 15a. The side straps 1S and 15a are received in and secured to stop blocks 16 and 16a, respectively.

The blocks 16 and 16a are mounted by appropriate means, such as an aperture 42, at each end of a substantially rigid rod which is generally parallel to the bars 11. The blocks 16 and :16u include a pair of stop means or upstanding lugs il and 46a. The rod 17 and the lugs 40 and 40a of blocks 16 and y'16a cooperate to prevent the holder 10 from being completely advanced through the platen as shown in FIGURE 3. Blocks 16 and l16a have a pair of members spaced to form slots -18 and 18a which face each other. These slots are of a width -to receive one or a pair of side straps and frictionally embrace the side straps placed therein. An upstanding stop blockv locking means or locking pin 19 and 19a is formed on each stop block. This locking means 19 is designed to cooperate with side strap locking means or holes 20 and 20a to vary the distance between the rod 17 and the most rearward bar 11a, thus adjusting the holder -10 for use with platens of different diameters.

3 The straps 15 and 15a are secured against accidental dislodgement by threading them through the slots 18 and 18a .in blocks i9 and 19a, respectively, and then impaling one of the series of holes Ztl and 20a over the pins L19 and 19a, respectively.

Also formed on the blocks 16 and 16a are inwardly projecting elongate fingers 21 and 21a which extend generally parallel to the rod 17 in spaced relation to form an enlarged spaced slot inwardly of the side straps for loosely embracing the marginal edges of continuous form stationery which has its opposite margins threaded through the respective slots. Slots 22 and 22a form the mounting means for loosely mounting the carbon holder on strips of continuous form stationery and maintaining the stationery in alignment with the holder le.

yThe inner edges 23 and 23a of the side straps -15 and a, respectively, are spaced exteriorly of the outer edges of the stationery 12. Thus whe-n the stationery is threaded through the slots 22 and then interleaved with the carbon paper by threading it through the slots 13, that portion of the holder 10 between the trailing bar 11a and rod 17 is left blank so that there is no superposing of the stationery l2 with the holder in the area under the typewriter platen. Thus, excesive bulk is eliminated and when it is desired to throw the platen out of frictional engagement with the stationery there is no excess of material located betwen those componen-ts to cause them to :rem-ain at least partially frictionally engaged.

Therefore, when a twist has completed typing one formlength of continuous form stationery she may throw the platen out of frictional engagement with the driving rollers and pull the stationery 12 forward one form length without meeting substantial resistance. The typist may then reverse the roll to a position where the next form length is ready to be typed, tear olf the completed form length and repeat the cycle. Also, due to the fact that the side straps 15 and 15a reside outside of the stationery 12 when it is linterleaved in the holder 10, the stationery and holder may be formed into an easily stored or easily shipped trim package in a pre-loaded condition. This is done by threading the stationery through a holder lll, minus the rod and stop blocks. The marginal material 14 and 14a and side straps 15 and 15a, being o=f exible material, may be folded down over the side over a zigzag folded stationery stack making va relatively trim assembly which may be easily stored or packaged. Once a typist has obtained one rod and stop block unit, it may be simply attached to the preloaded carbon holder in each subsequent stack of stationery.

When it is desired to make more multiple copies than can be accommodated by one holder '10, a pair of holders may be combined in order to produce more multiple copies of continuous form length asshown in FIGURE 2. ln this case a holder 16a is used in addition with holder 10, the holder lila not including the trailing bar illa and having carbon ysheets 12 secured to each of its bars 11. The holder 10a is positioned vertically with respect to holder l0 so that the carbon bearing bars 1l of lholder 10a are in register with the carbon bearing bars 11 of holder 10. The side straps of the holders ylll and 10a are secured to a common pair of stop blocks i6 Iand 16a mounted on a single rod 17. Thus, with the iaid of a single rod and one pair of stop blocks the device may be converted into an apparatus capable of producing twice the number of multiple copies.

` This new improved carbon holder overcomes inherent defects found in the prior devices for this purpose. The present device is so constructed that when interleaved with continuous form stationery and mounted for use in a typewriter, it is possible for the typist to easily manually pull the continuous form stationery forward when the typewriter platen has been frictionally disengaged Vfrom the driving rollers of the typewriter. Furthermore,

thisholder is adjustable `and therefore may be used with Vseveral typewriters which may have platens of different diameters. By securing carbon sheets of different lengths to the carbon holding bars, this holder may be used with dilerent strips of continuous form stationery which have different individual form lengths. Also, by taking a stack of continuous form stationery and threading the first form length through the holder of this invention which does not have the rod and stop blocks attached thereto, and then folding the marginal material on side straps down over the stack of stationery, a preloaded unit of material is prepared which may be easily stored or shipped in a form which is semiready for use in a typewriter. The device is so constructed that it may be used with similar holders and mounted on la common bar to increase the multiple plies of carbon copies of continuous form stationery which may be produced in a single typing. The convenience and economy of the new device is another outstanding feature. The rod 17 and stop blocks 16 and 16a which are mounted thereon are substantially permanent `articles which `are vkept by the typist. The remainder of the holder li?, which has the carbon material secured thereon, is of inexpensive material. Thus, when the consumable carbon paper l2 noy longer can type clear carbon copies, or has been spent, that portion of the device is simply detached from the stop blocks and rod and thrown away and another portion is substituted therefor.

While -l have shown and described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in

the construction and arrangement may be made without departing from the spirit and the scope of the invention as disclosed in the appended claims.
